Hi everyone, I'd like to know how to generate a set of random numbers with normal distribution (randn) belonging to a range defined by me.
To make it easier:
I want to generate 10 random numbers between [-0.5 0.5] using randn.
Thanks for your attention

Good. Here it is as an 'official' answer:
pd = makedist('Normal');
t = truncate(pd,-0.5,0.5);
r = random(t,10,1);

a = -0.5 ;
b = 0.5 ;
N = 10 ;
r = (b-a).*randn(N,1) + a;

If that would work, then I guess this is what you are after:
pd = makedist('Normal');
t = truncate(pd,-0.5,0.5);
r = random(t,10,1);
